: For an individual to "own" an old military sub, it typically must be a non-profit museum venture. The U.S. Navy, for instance, requires a maintenance plan and reserves the right to reclaim the vessel if it isn't properly cared for. Feasibility and Costs

: Moving a massive hull requires expensive tugboat services. Once situated, docking fees and maintenance can cost upwards of $25,000 per month.

Acquiring a submarine is only the first expense; the logistics of moving and maintaining it are staggering.

: A decommissioned, stripped hull might cost as little as $150,000, while a more intact, older diesel-electric boat (like a Russian Foxtrot-class) could reach several million dollars.

Because of the high cost of making them dive again, most old submarines find new life as stationary structures. U.S.S. Albacore - OTIS (Odd Things I've Seen)

The market for military submarines is divided by technology and intent. Nuclear-powered submarines (such as the U.S. Virginia-class or British Vanguard-class) are never sold to the public because their propulsion systems and materials remain highly classified and hazardous.

: Most decommissioned vessels are destined for the scrap yard to be recycled. A small percentage are preserved as museum exhibits , allowing the public to see engineering marvels like the USS Albacore .
